DELL, a

type machines of the general character set forth in Letters Patent oftheUnited States, No. 436,532, to O. Mergenthaler, wherein the slug orlinotype is cast in a slotted mold and is then delivered therefrom by areciprocating ejector blade, which advances through the moldv from therear, forcing the slug before it through the trimming mechanism to thereceiving galley at the front of the machine. The ejector blade isconnected to the front end of a horizontally movable slide, theconstruction being such that it may be readily detached therefrom topermit the substitution of another of different dimensions.

In the commercial linotype machine, the ejector slide is mounted on asecond slide which carries the mold wheel at its outer end. In order toeffect certain adjustments and for various other purposes not necessaryto state herein, it is frequently necessary to draw the ejector slidemanually forward to bring. it to a convenient position for the desiredmanipulation. In the past, this result has been accomplished in avariety of ways. For example, in order to advance the blade to therequired position, the operator has left his place at the machine andturned the actuating cam and connected parts by hand; or he hasdisconnected the link from the ejector lever by the removal of the con--necting pin; or in another instance the ejector slide has been providedwith a movable latch to permit its disconnectionfrom the link. In mypresent form, I provide improved means whereby the link may be readilyconnected to or disconnected from the actuating lev'er at will, theparts being so constructed and arranged as to prevent their accidentaldisplacement both in operative and inoperative position.

In the accompanying drawing, I have shown my invention in preferredembodiment and by way of example, and as adaptresiding at In theaccompanying drawing F igure 1 is a side elevation of the mold wheel,mold slide, ejector slide, and its actuating link and lever, having myimprovement embodied therein; Fig. 2 is an enlarged detail, illustratingthe improved latch in operative condition; Fig. 3 is a similar view ofthe latch in detached position; and Fig. 4 is a section on the line 4-4of Fig. 2. a

The mold slide A carries the mold wheel B, and also the ejector slide 0,which is reciprocated with relation thereto by the actuating link D andejector lever E in the usual manner, as in the ordinary commerciallinotype machine, or as illustrated for instance in numerous LettersPatent of the United States, such as No. 945,609 to J. R. Rogers. Thelink D is connected to the lever E by the pin F mounted in the latter,and to permit the ready engagement and disengagement of the parts forthe purposes previously indicated, I have provided the link withconnecting means which are now to be described. The link D is formed atits rear end with the vertical notch D- to engage the pin F. The end ofthe link is also provided with the relatively movable latch 1 formedwith the horizontal notch J which also engages the pin F, and wherebythe link is securely held in relation thereto, when the parts are intheir operative condition. The end of the link D is bifurcated, (seeFig. 4), and the latch G is located therein, it being pivotally mountedupon the transverse'pin H which passes through the longitudinal slot G,this arrangement permitting two movements of the latch with reference tothe link, pivotally about the pin and also longitudinally to the extentpermitted by the length of the slot.

The latch G is formed at its inner end with the inclined or beveledsurface K, and the link D with the correspondingly inclined or beveledsurface L, a spring M being also provided, connected at one end to thelatch and at its other end to the link, in such manner that when theparts are inoperative condition I (see Fig. 2), the spring holds the twosurfaces in contact and thereby prevents the accidental disengagement ofthe parts. At this time, the end of the link D is held against verticaldisplacement by the engagement of the horizontal slot J of the latch Gwith the pin F, and the end of the slot G isin close relation tothepivotal pin H. This position of the parts continues until the latch G'ismoved longitudinally (see Fig. 3), and the other end of the slot G isbrought into relation to thepin H, at which time the disengagement ofits notch J from the pin F and the separation of the surfaces K and Lpermits the pivotal movement of the latch, when the end of link D may beelevated to free its notch D from the pin F. The e ector slide C may nowbe moved at will for the purposes of blade substitution or otherwise.

It is to be noted that due to the combined longitud nal and pivotalmovements of the latch with reference to the link, the parts whenshifted either to operative or inoper-.

ative position, pass center and are then securely held in substantiallythe same manner as in the well-known jackknife joint. Moreover, thespring M acts to move the parts to their final position when manuallystarted in either direction. For instance, if the latch be in thelocking position, as shown in-Fig. 2, and if it be moved longitudinallyand then slightly tilted upward, the spring immediately snaps it to theunlocking position, as shown in Fig. 3. Or if from the latter positionthe latch be tilted downward, the spring draws it home and restores itto the locking position.

As previously stated, I have shown my in vention only in preferred formand by way of example, but obviously many modifications and variationstherein, as well as in its mode of application, will suggest themr I.Miss,

selves to those skilled in the art without departure from its scope.

Having thus described my invention, its construction and mode ofoperation, what I claim and desire to secure by Letters Patent of theUnited States, is as follows:

1. In a linotype machine, the combination of the ejector slide, itsactuating lever, and the intermediate connecting link, the lever beingprovided with the pin F to engage the link randjche link. carrying themovable latch G- which engages beneath the pin F and thus serves toprevent the disengagement of the link from the pin.

2. In a linotype machine, the combination of the ejector slide, itsactuating lever, and the intermediate connecting link, the lever beingprovided with the pin F to engage the link, and the linkcarrying themovable latch G formed with the slot J to straddle the pin and thusprevent the disengagement of the- .G formed with the horizontal slot Jto en gage the pin.

4. In a linotype machine, the combination of the ejector slide C, linkD, and actuating lever E, the said lever being provided with the pin Fto engage the link, and the link being providedwith the pivotally andlongitudinally movable latch G to engage said pm.

5. In a linotype machine, the combination of the ejector slide C, linkD, and actuating lever E, the said lever being provided with the pin F,and the link being formed with the vertical slot D to engage the pin andprovided with the longitudinally and pivotally movable latch G formedwith the notch J to engage said pin.

6. In a linotype machine, the combination of the ejector slide C, linkD, and actuating loved E, the said lever being provided with the pin Fto engage the link, and the link being provided with the pivotally andlongitudinally movable latch G to engage said pin, together with thespring M to hold the latch in both operative and inoperative position.

7. In a linotype machine, the combination of the ejector slide C, linkD, and actuating lever E, the said lever being provided with the pin F,and the link D being notchcd at D to engage the pin and provided withthe surface L, together with the longitudinally and pivotally movablelatch G connected to the link and formed with the notch J to cngage thepin, and formed with the surface K to engage the surface L on the link,and thekspring M connected to said latch and lin 8.
